| Challenge: | ProUIE improves universal information extraction (UIE) without external information . many LLM-based methods rely on extra schema cues, external resources or complex alignment and verification pipelines . |
| Approach: | They propose a Macro-to-Micro progressive learning approach that improves UIE without external information. |
| Outcome: | ProUIE outperforms instruction-tuned baselines on average for NER and RE while using a smaller backbone. |
A Transformer-based Threshold-Free Framework for Multi-Intent NLU (2022.coling-1)
Copied to clipboard
| Challenge: | Existing models for multi-intent natural language understanding mainly detect multiple intents on threshold settings. |
| Approach: | They propose a transformer-based multi-intent NLU model with multi-task learning that exploits the information of the number of multiple intents in each utterance without additional manual annotations. |
| Outcome: | The proposed model achieves superior results on two public multi-intent datasets. |
